An IP (Internet Protocol) Address is a 32 bit number broken into four (4), eight (8) bit sections. Each section is converted from the binary equivalent to a decimal number. When the IP Address is broken into 4 sections the decimal number ranges from 0 to 255.

The most common format for an IP Address is show as 10.1.1.1, however the address can be written out as one large number like 32-bit 167837953. This method of displaying IP Address was once used to trick people into visiting web sites with questionable content.

For SSL Certificates to function, each SSL Certificate must be installed on a unique IP Address and Port combination. For example 10.1.1.1:443 (port 443) 10.1.1.1:8443 (port 8443) could each have an SSL Certificate installed or 10.1.1.1:443 (port 443) and 10.1.1.2:443 (port 443) would also be valid for installing an SSL Certificate.
